Objective To explore the effects of wearing ankle-foot orthoses (AFOs) on motor function in children with spastic cerebral palsy (SCP). Methods Fifty-two children with SCP were randomly divided into a wearing-for-training group (n = 16, group 1 ), a day-wearing group (n = 19, group 2) and a day-night-wearing group (n = 17, group 3). In addition to the conventional rehabilitative treatment given to all participants, the children in group 1 wore AFOs during movement training, and children in group 2 wore AFOs in the daytime for 6-8 h per day, while AFOs were applied to the children in group 3 for 24 hours a day except for cleaning and during certain training routines. All the treatments were continued for 2 months. Clinical assessments included the range of passive ankle dorsi-and plantarflexion (APROM) , modified Ashworth scale (MAS) ratings, and the D and E dimensions of the Gross Motor Function Measure (GMFM). All were performed before and after treatment. Results Before treat-ment, no statistically significant differences were found among the three groups in terms of APROM, MAS, or GM-FM. There were significant subsequent improvements in groups 2 and 3 when compared with group 1 in terms of APROM, MAS and GMFM results. Group 2's improvements in APROM and MAS results were not significantly better than those of group 3, but their average GMFM score improvements were significantly better. Conclusion Wearing AFOs in the daytime 6-8 hours per day is more effective in reducing spasticity and improving functional performance in children with SCP.

Objective This objective of the study was to analyze the factors related to being recaptured and condom use among low-fee female sex workers (FSWs) to provide reference in developing human immunodeficiency virus (HIV) intervention strategy. Methods Physical examination certificates were designed by Zhongshan County Center for Disease Control and Prevention to record HIV and syphilis test results for low-fee FSWs from 2013 to 2015. Low-fee FSWs were asked to show physical examination certificates in the next intervention and test. Multivariate Logistic regression was used to analyze factors associated with being captured with physical examination certificates. Generalized linear mixed model was used to analyze factors associated with condom use with clients. Results A total of 220 low-fee FSWs were recruited by using physical examination certificates and received 389 interviews from 2013 to 2015. The proportions of HIV positive and syphilis positive were 4.2% (9/213) and 30.0% (64/213) respectively among those who had HIV and syphilis test. Results of multivariate Logistic regression analysis showed that low-fee FSWs who had been FSWs for more than 4 years (OR=2.95, 95% CI：1.35-6.45), and worked in the local county in the past 30 days (OR=11.74, 95% CI: 5.26-26.20), were more likely to be captured with physical examination certificates. Results of generalized linear mixed model showed that those who were captured at least once (OR=3.33, 95% CI: 1.34-8.27), had junior middle school education and above (OR=22.79, 95% CI: 3.75-138.57), had high HIV knowledge (OR=3.57, 95% CI: 1.52-8.38), and charged more than 30 yuan for vaginal sex (OR=30.68, 95% CI: 12.57-74.90), were more likely to use condom consistently. Conclusions Physical examination certificates could be used for low-fee FSWs surveillance and intervention and tracking their HIV and syphilis status. The intervention strategy should take these into consideration.

OBJECTIVETo study the relationship between gene p53 codon 72 polymorphism and pathological scar formation occurrence after caesarean section.

METHODSThe method of molecular beacon with real-time PCR was applied to detect gene polymorphism of p53 codon 72 in blood samples taken from 303 pregnant women (within a week after caesarea section). The clinical visits were taken 3 times for 12th to 18th months to ascertain clinical formation of pathological scar and its relationship to genotype of p53. The chi-square method was used to analyze the relationship of p53 gene polymorphism and abnormal scar formation occurrence by statistical software SPSS 13.0.

RESULTSTotal of 303 pregnant women were assayed. 30 patients were found with pathological scar by clinical visit in the total 303 pregnant women. The genotype frequencies of total three types (C/C, C/G and G/G) of p53 gene codon 72 in patients with pathological scar are significantly different from that of normal pregnant woman. The frequency of C/C genotype in patients are higher than that of normal pregnant women (P < 0.01). The frequency of C/C genotype in these patients with pathological scar is higher (46.7%, 14/30) than C/G (33.0%, 10/30, P < 0.01) or G/G (20%, 6/30) genotype (P < 0.01). The C allele frequency in the patients is 63.7%. It is also higher than G allele (36.7%, P < 0.01). The OR value is 2.30. Therefore the C allele of p53 gene codon 72 is a risk factor for pathological scar.

CONCLUSIONSThere was a certain relationship between p53 gene codon 72 C allele and pathological scar formation after caesarean section.

OBJECTIVETo investigate the expression of RRM1 and ERCC1 genes in tumor tissues and peripheral blood lymphocytes of advanced non-small cell lung cancer (NSCLC).

METHODSTissue and peripheral blood samples were collected from 49 advanced NSCLC patients treated with gemcitabine plus carboplatin. The expressions of RRM1 and ERCC1 mRNA in tumor tissue and peripheral lymphocytes were detected by real-time fluorescent quantitative PCR. The relationship of gene expression with clinical characteristics,chemotherapy response and prognosis was analyzed.

RESULTSThe RRM1 expression in tumor tissues was positively correlated with that in peripheral blood lymphocytes,while no significant correlation was observed between ERCC1 expression in tumor tissues and that in peripheral blood (rs=0.332 and 0.258; P=0.020 and 0.073, respectively). The expression of RRM1 and ERCC1 in tumor tissues peripheral lymphocytes was synchronous (rs=0.634 and 0.351; P<0.001 and 0.013, respectively). There was no significant correlation of gene expression with gender, age, smoking status, performance status, clinical stages and histological types of patients (P>0.05). Significant difference was found in response rate to chemotherapy (P<0.05,P<0.01,P<0.05),median survival time (P<0.05,P<0.01,P<0.05) and 1-year survival rate (P<0.01,<0.05,P<0.05) between patients with low RRM1 and ERCC1 expression levels in tumor tissues or low RRM1 expression levels in peripheral blood and those with high RRM1 and ERCC1 expression levels. The patients with low ERCC1 expression levels in tumor tissues gained higher 2-year survival rate (P<0.05). There was no correlation of the expression of ERCC1 in peripheral blood with the response to chemotherapy and prognosis (P>0.05).

CONCLUSIONThe expression of RRMI and ERCC1 genes in tumor tissues and RRM1 in peripheral blood lymphocytes is closely correlated with the response to chemotherapy and prognosis of patients with advanced NSCLC treated with gemcitabine plus carboplatin.

OBJECTIVETo study the expression of CXCR4 in acute leukemic cells and its clinical significance.

METHODBone marrow samples from 73 acute leukemia patients and leukemic cell lines were investigated by flow cytometry (FCM), the expression of SDF-1 in human marrow stromal cells and meninges were studied by using reverse transcription polymerase chain reaction (RT-PCR). Adhesion, migration and invasion of U937, NB4 and K562 cells were studied in vitro.

RESULTSThe expression rates of CXCR4 in ALL and AML patients was 65.6% and 17.1%, respectively. And it was 0.2%, 41.0% and 52.0% in K562, U937 and NB4 cells, respectively. The extramedullary infiltration rates were 61.9% and 18.2% for CXCR4 positive and negative groups of ALL, respectively (P < 0.05); while in AML, the number of peripheral white blood cells in CXCR4 positive group was lower than that in CXCR4 negative group (P < 0.05). SDF-1alpha could enhance the adhesion, migration and invasion capacity of leukemic cells in vitro.

CONCLUSIONOverexpression of CXCR4 in AL cells might be the molecular mechanism of extramedullary infiltration in leukemia.

AIMTo study the antitumor mechanism of 3-bromopropionylamino benzoylurea (JIMB01) on leukemia and lymphoma.

METHODSThe antitumor effects of JIMB01 in cell culture was detected by MTT staining. JIMB01-induced apoptosis in leukemia and lymphoma cells was tested by Giemsa staining, fluorescent Hoechst33258 staining, as well as DNA gel electrophoresis. Cell cycle was analyzed by flow cytometry. JIMB01-induced Bcl-2 phosphorylation in CEM cell lines was detected by Western blot methods. The activities of caspase-3 and caspase-8 were determined by colorimetric protease assay and that of caspase-9 was determined by fluorescent intensity.

RESULTSThis compound showed antiproliferative activities in a panel of nine human leukemia and lymphoma cell lines with IC50 values in the range of 0.25 micromol x L(-10 to 0. 51 micromol x L(-1). Morphological observation and cell cycle analysis indicated that CEM cells were blocked at mitosis phase by JIMB01. The fluorescent Hoechst33258 staining showed apoptotic nuclear degradation dispersed in the cytoplasm of CEM cells exposed to JIMB01 at 0. 80 micromol x L(-1) for 24 h. DNA degradation in the form of a multiple-unit DNA ladder was clearly demonstrated in CEM leukemia cells treated with JIMB01 at 0.15 micromol x L(-1) or higher for 24 h using agarose gel electrophoresis. Bcl-2 phosphorylation became visible, in Western blot, within 6 h in CEM cells treated with JIMB01 at 0.15 micromol x L(-1) or higher for 24 h. JIMB01 increased the activities of caspase-3, -8 and -9 in CEM cells; DEVD-fmk, a caspase-3 inhibitor, inhibited the cytotoxicity of JIMB01 in CEM leukemia cells.

CONCLUSIONThe antitumor mechanism of JIMB01 is that JIMB01 may induce tumor cell apoptosis through Bcl-2 phosphorylation and then caspase passway.

OBJECTIVETo investigate the influence of tissue inhibitor of metalloproteinase 2 (TIMP-2) on the infiltrative patterns of human monocytic leukemic cell line SHI-1 in nude mice.

METHODS1) 1 x 10(7) TIMP-2 gene transduced SHI-1 (SHI-1-TIMP-2) and SHI-1 transduced MSCV gene (SHI-1-MSCV) cells were inoculated via tail vein into 6-week nude mice, which pretreated by splenectomy, cytoxan intraperitoneal injection, and sublethal irradiation(referred as SCI nude mice). 30 days after inoculation, half of the mice were sacrificed, and the infiltration patterns were investigated by histological exam and human CD45 immunohistochemistry, other mice were observed for survival time. 2) Leukemic cells inoculated subcutaneously into the axillary area of mice without any pre-treatment. On day 23 and 30, mice were sacrificed to measure the volume of neoplasm. TIMP-2 protein expression and the micro vein density were detected by immunohistochemistry.

RESULTSIn SCI nude mice inoculated via caudal vein with SHI-1-TIMP-2 cells, the survival time was shorter and infiltration (including in central nervous system) was higher than that in those inoculated with SHI-1-MSCV cells. However, in inoculated subcutaneously group, the neoplasm though grew rapidly at first, over expression of TIMP-2 limited the tumor growth and angiogenesis.

CONCLUSIONThe functions of TIMP-2 are diversity; the role of TIMP-2 in tumor infiltration and metastasis was worthy of further investigation.
